不过找到了这行字

Effective after the close of business on May 11th, 2018, Fidelity will execute a 10-for-1 share split on each Class of the Fund. As a result of the split, the number of outstanding shares has been multiplied by 10, with a proportionate decrease in the Net Asset Value (NAV) per share。

 

所以俺估计是系统问题，没把the number of outstanding shares 搞对。

谢谢！
